Specific meanings of the above terms in the embodiments of the present invention can be understood by those of ordinary skill in the art according to specific situations.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The processing steps of the air conditioner sheet metal part processing method are described below with reference to fig. 1-5.
As shown in fig. 1, the middle of the casing 1 of the outdoor unit of the air conditioner is a circular air guiding ring 11, and the first sheet metal part 2 and the second sheet metal part 3 are placed in the air guiding ring 11. It should be noted that fig. 1 is only an example, and it is understood that one or more sheet metal parts may be placed in the wind guiding ring 11. In the traditional course of working, directly retrieve as the waste material after dashing circular wind-guiding circle 11, material cost is high or shift to and process into other sheet metal components on another mould, and the mould is a lot of and leads to the processing cost height.
The embodiment of the invention provides an air conditioner sheet metal part processing method, which comprises the following steps:
step S1, placing the raw material of the encloser under a die, and stretching or punching the corresponding area of the air guide ring 11 to form the convex hull and/or the rib position of the first sheet metal part 2. That is, the same die is used to punch or stretch the first sheet metal part 2 while processing and manufacturing the housing raw material. The structure of the shell stock after the die operation is shown in fig. 2.
Step S2, the structure of the wind guide ring 11 except the first sheet metal part 2 is punched off by the die to separate the housing 1 and the first sheet metal part 2. The die is used for stamping the housing raw material and punching the housing raw material to form the air guide ring 11, wherein the area corresponding to the first sheet metal part 2 is not punched, and therefore the first sheet metal part 2 is separated from the housing 1. Fig. 3 is a structural view illustrating the separation of the first sheet metal member 2 from the housing 1 after the step S2 is performed. It will be appreciated that the first sheet metal part 2 and the housing stock are still in the mould and are subsequently processed by the same mould.
Step S3, the housing 1 and the first sheet metal part 2 are bent and flanged to complete the machining and forming of the first sheet metal part 2 and the housing 1. The sheet metal part after being formed is shown in fig. 4.
According to the air conditioner sheet metal part processing method provided by the embodiment of the invention, one or more relatively small sheet metal parts are added in the large-size sheet metal mould vacant position by means of the same mould, and compared with the traditional processing and manufacturing method, the smaller sheet metal parts are not required to be independently processed under another mould, so that the raw material consumption is reduced on the premise of not increasing the mould size, and the material cost and the processing cost are saved.
Specifically, step S3 specifically includes bending the buckle 12 of the housing 1 and the side surface of the first sheet metal part 2, and flanging the air guide ring 11 of the housing 1 and the flanging hole of the first sheet metal part 2. The sheet metal part after the operation is shown in fig. 5. Then, the side surface of the housing 1 is bent, the air guide ring 11 of the housing 1 is reamed, and the first sheet metal part 2 is bent. As shown in fig. 5, the buckle 12 of the housing 1 is located at the periphery of the wind guide ring 11, the buckle 12 of the housing 1 is bent by means of a mold, the processing operation of the buckle 12 is completed, meanwhile, two opposite side surfaces of the first sheet metal part 2 are bent, and the hole structures on the housing 1 and the first sheet metal part 2 are flanged, so that the holes and the edges on the housing 1 and the first sheet metal part 2 are flanged and bent simultaneously by means of a movable mold and a static mold in the same mold, then the movable mold is adjusted, and the final molding operation is performed on the other side surfaces and the holes of the housing 1 and the first sheet metal part 2.
In step S3, the bending of the side surface of the housing 1 includes bending both side surfaces of the housing 1, and the bending of the first sheet metal part 2 includes bending both side surfaces of the first sheet metal part 2.
In addition, in order to facilitate the punching slip of the scrap in step S2, step S1 further includes: and pre-stamping the housing raw material.
As shown in fig. 2, in the air conditioner sheet metal part processing method provided by the embodiment of the present invention, in step S1, convex hulls and rib positions of the first sheet metal part 2 and the second sheet metal part 3 are simultaneously formed on the housing raw material through a mold; correspondingly, in the step S2, the sheet metal part is punched off to separate the housing 1, the first sheet metal part 2 and the second sheet metal part 3; in step S3, the bending operation and the flanging are performed on the housing 1, the first sheet metal part 2, and the second sheet metal part 3. The structures of the first sheet metal part 2 and the second sheet metal part 3 can be the same or different. When first sheet metal component 2 is the same with 3 structures of second sheet metal component, both can be the mirror image and distribute, also can the array distribution. When the first sheet metal part 2 and the second sheet metal part 3 are different in structure, it can be understood that the sizes of the first sheet metal part and the second sheet metal part are smaller than the size of the wind guide ring 11.
For example, first sheet metal component 2 and second sheet metal component 3 are square parts, and the axis of first sheet metal component 2 and the axis of second sheet metal component 3 are located the central line of housing raw materials. Therefore, the dies are symmetrically arranged along the middle line in an opposite mode, and the operation is more convenient.
As shown in fig. 2, in step S1, the die is pressed to form annular convex hulls and/or ribs on the raw material of the casing in the area corresponding to the wind guide ring 11. For example, the convex hull may be formed by stamping, or the convex hull and the rib position may be formed simultaneously in the corresponding region of the air guide ring 11 by stamping, specifically, according to the structure of the first sheet metal part 2. The annular convex hull and/or the rib position may be a circular ring shape or a closed shape formed by other linear bodies, which is not particularly limited.
As shown in fig. 3, the annular convex hull and/or rib is flat on one side and pre-punched on the flat side for subsequent punching to form the notch.
In the air conditioner sheet metal part processing method provided by the embodiment of the invention, the structure of the air guide ring 11, except the first sheet metal part 2, punched off by the aid of the die in the step S2 specifically comprises the steps of slitting the region to be punched off by the aid of the die, punching, sliding and punching in the circumferential direction of the air guide ring 11 to form the buckle 12. And after the to-be-punched area is cut by the die, the punching effect is optimized.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
